Normally when it comes to wireless headphones I just have to put on the largest earhook and in-ear headphones and they fit perfectly. None of the parts included in the kit allowed the headphones to fit in my ears. Not only did they fall out, but they weren't comfortable enough to hold. Not for me. I tested them for sound and they worked, but I can't confirm the sound quality as I didn't have a good fit in my ears.
